Application filed November 14, 1910. Serial No. 592,412.

To all whom it may concern:

Be it known that I, EDWARD F. Karrie, citizen of the United States,residing at St. Joseph, in the county of Buchanan and State of Missouri,have invented certain new and useful Improvements in Acetylene-GasGenerators, of which the following is a specification, reference beinghad therein to the accompanying drawing.

My invention relates to improvements in acetylene gas generators, andthe objects of my improvements are, first: to so construct an acetylenegas generator, that the operator thereof, in recharging the same, cannot take the generator bell from the generator, until the gas thereinhas been forced therefrom through gas conducting means into storingmeans, back-flow of said gas from said storing means is prevented, waterfeeding means for said generator is closed, residual pressure of gas insaid bell and generator has been exhausted therefrom into the open air,and a waste water cock has been opened for draining of water from saidgenerator; and to render it impossible for said operator toinadvertently liberate gas from said machine, while performing theoperations of recharging the same :second; to so construct waterconducting means and controlling means therefor, that after theoperations of recharging and returning the parts to normal position havebeen performed by said operator, the water fed into said generator shallbe so controlled that an abnormally large amount of gas shall not begenerated: third; to provide machine controlling means, operable eitherat the machine, or at any desired point distant therefrom, whereby thegas generated and stored in the machine, can be promptly exhaustedtherefrom, into the outside atmosphere when desired, and the furthergeneration of gas and consequent consumption of carbid in the generatorbe stopped; thus providing ,means for safety from escaping gas andfurther generation of same, in case of fire fourth; to so construct theparts of the wa ter controlling means, that feeding of water into saidgenerator is stopped by said generator bell, when... the same is nearingthe lowest point of its downward travel; thus providing means by whichsaid water is conserved and flooding of the floor on which the machinestands is prevented :fifth; to provide overflow conducting means wherebythe height of water in said generator and around said bells is limitedand waste water therefrom is directed into vessels, adapted to receivethe same. I attain these objects by the mechanism illustrated in theaceompanying drawing, in which Figure l is a side elevation of themachine as it appears when in use. Fig. 2 is a top plan, certain partsbeing broken away to avoid obscurity. Fig. 3 is a horizontal section onthe line X X, seen in Fig. 1, looking downward. Fig. 4 is a verticalsection of the gas directing cock and its pipe connections, on the lineY Y, seen in Fig. 3, looking toward the right. Fig. 5 is a verticalsection on the line Z Z, seen in Fig. 2, looking from the rear of themachine, showing the valve lever gravitating and the other parts inposition for recharging. Fig. 6 is a top plan of a carbid pan and of thepan retainer. Fig. 7 is a top plan of the generator compartment and ofthe generator bell, the latter being in position to be rotated laterallyand removed from said generator. Figs. 8, 9 and 10 are enlarged sectionsin detail similar to Fig. 1, showing the three positions of the gasdirecting cock gate. Fig. 11 is an enlarged section in detail of one ofthe bell guiding means, cut horizontally on the line W V seen in Fig. 1,looking downward. Fig. 12 is an enlarged section in detail of the valvelever rod and its guiding means, cut horizontally on the line V V seenin Fig. '1. Fig. 13 is an enlarged verti cal section through the centerof the water controlling valve, and a perspective view of certain otherparts, related thereto. Fig. let is a perspective view similar to Fig.13 with the valve omitted and the latch held clear of the bell bracketby the lower end portion of the valve lever. Fig. 15 is an enlarged sideelevation in detail of the scrubber cap. Fig. 16 is a vertical sectionon the line U U seen in Fig. 2, looking toward the left.

Figs. 17 and 18 show one of the other various forms in which the bellguiding means may be constructed.

Referring to Fig. 5, in the generator tank 1, is the water seal 1, inwhich is submerged the lower end portion of generator hell 2, adapted tobe raised by pressure of gas therein and to be lowered by the gravitythereof. Said gas is generated in carbid pans 8, mounted on the ordinaryopen stand 4 in generator compartment 5, and held down thereon byelastic pan retainer 3, (see Fig. 6,) having the return bent handleportion 3, adapted to be gripped in the hand of the operator, (notshown,) thereby compressed inward and placed with the outer ends thereofin groove 5 formed around and in the upper end portion of generatorcompartment 5, seen in Fig. 5. Referring to Fig. 5, compartment 5 holdsfeed water 10 which is fed into the same around said carbid pans, andthe height of which is limited by overflow pipe 10, adapted'to directwater therefrom into bucket 7 Said compartment 5 is provided with feedwater inlet pipe 6, connected by four-way fitting 6 with pipe 7,connected by fourway fitting 7 (see Fig. 1,) with pipe 8, connected byglass tube water gage 9 with pipe 9, closable by feed water cock 9,having rotatable cock stem 9. Said pipe 9 has its upper end connectedwith tank 10 and is provided with the automatically operated controllingvalve 11, (see Fig. 13,) for controlling flow of water through thedescribed water conducting means, through which water is fed from tank10 into generator compartment 5. Said water rises around carbid pans 3and flows through notches 3 formed in the upper edges thereof ontocarbid 3", thereby genera-ting gas, the thus generated gas passes outthrough said notches and into bell 2, causing said bell to rise. Pipe22, (see Fig. 3,) connects fitting 6 with fitting 22, with which thelower end of guide 22 is connected.

Referring to Fig. 13, valve 11 is provided with valve stem 1 1 and withthe annular perforated lower valve guide 12, secured to pipe 9.Apertured cap 13 covers opening 13, formed through the top of tank 10,and has stem 14 passed through the aperture in said cap as an upperguide for said valve and its stem. Referring to Fig. 1, the upperextremity of said stem is pivotally connected by pivot 15 with one endof valve lever 16, provided with weight 16 formed on the free endthereof and projecting over the center of bell 2. Said weighted end isadapted to be lifted by said bell for closing said valve, and to belowered by the gravity thereof for opening the same. Pawl 18, providedwith pawl lever 18, overbalance weight 18" and stop stud 18 is pivotallysecured by pivot 19 to lever 16. Upright 17, provided with ratchets 17has its lower end secured on tank 10 and projects upward therefrombetween lever 16 and pawl lever 18, which form a guide for slidablyguiding said lever in its hereinafter described upward and downwardrotation on pivot 15. Ratchets 17 are adapted to engage pawl 18. Upright17 has stop pin 17 in the upper extremity thereof, adapted to stop andlimit the upward rotation of lever 16. Rigidly secured on valve stem 11, (see Fig. 13,) is the projecting arm 19, provided with the dependingarm member 19, se-

cured to the outer end thereof. To the lower end of said member 19, thelatch 20 is pivotally secured by pivot 20. Said latch is provided withdisengaging finger 20, extending laterally from the upper edge thereof,and behind said depending member 19 and adapted to limit the downwardrotation of latch 20 on its pivot 20. Said finger is adapted to becontacted and rotated by weighted end 16 of lever 16, from the positionseen in Fig. 13 to the position seen in Fig. 14:, for removing latch 20from the path of bracket 21, secured on and carried by bell 2. Saidbracket is normally adapted to press downward upon said latch andthereby close valve 11, when said bell is fully lowered as seen in Fig.13, and while lever 16 is in the position seen in Fig. 1, but supportedby pawl 18, engaged with a ratchet 17. The previously described actionof lever 16 on latch 20 takes place when said lever is lowered ashereinafter described, and the former takes place when all of carbid 3is exhausted and all of the gas in bell 2 is used therefrom.

Generator hell 2, in its upward and downward travel is guided by thefollowing described bell guiding means, seen in Figs. 1, 7 and 11. Bellguide 23 has its lower end secured to tank 1, extends upward therefromand terminates in return bend 23 from whence said guide extends downwardas guide 23". Guide 22, return bend 22 and guide 22" are similarlyformed and secured. The lower ends of guides 22 and 23 are concaved asseen at 22 and 23, in Fig. 1, and terminate leaving spaces 22 and 23below said concaved ends, through which flanged guide wheels 24 arepassed by lateral rotation of hell 2, for removing said bell from thedescribed generator.

Referring to Fig. 11, said wheels are rotatably mounted on the roundedshank ends 25 of handle bar 25, secured on the top of bell 2. Saidwheels are retained in place thereon by handles 25", secured on saidshank portions, and are adapted to travel between and be guided by thedescribed guides, thereby providing anti-friction guiding means forguiding bell 2. Should lever 16, from any cause fail to limit theupward. movement of said bell, the same is stopped by return bends 22and 23 which stop the described wheels in their upward travel. Bell 2 isprovided with gas conducting pipe 26, (see Fig. 5,) which extendsdownward from a point above the level of the top of compartment 5,through the open bottom of said bell and through the bottom of tank 1,and is connected by T fitting 26 with pipe 27, connected with gasdirecting cook 28, having cock gate 29 rotatable therein.

Pipe 6 is provided with gas tight plug 6 therein and connects fitting 6with fitting 26, seen in Fig. 3. When said cock gate is in the positionseen in Figs. 4, and 8 the same directs gas from the described generatorinto pipe 30, by which said cock is connected with four-way fitting 31.Gas inlet pipe 32 extends upward from said fitting 31, through thebottom of water seal tank 33, provided with water seal 33 therein, inwhich the lower open end of storage bell 34 is submerged. Pipe 31,having plug 31 therein, connects fittings 31 and 54. Surrounding theupper end of pipe 32, (see Figs. 2, 5 and 15) is the water seal cap 35,the lower end of which is submerged in water seal 33, and provided withapertures 35 formed therethrough, for spraying gas, as the same passestherethro-ugh into water seal 33, for cleansing and cooling said gas.Said cap also provides water sealing means, whereby the upper end ofpipe 32 is at all times sealed; which prevents return fiow of gas fromstorage bell 34 into the previously described generator. The describedparts form gas conducting means, whereby gas is conducted from generatorbell 2 into storage bell 34. From said bell gas is conducted to anydesired system of gas distributing pipes, not shown, through thefollowing described gas outlet means.

Referring to Fig. 16, said gas passes into the upper end portion offilter pipe 78, thence through apertures 78 through said pipe, intofilter 7 9, downward therethrough and thence through apertures 78" intothe lower end portion of said filter pipe, (provided with gas tight plug78 therein between said apertures,) thence through fourway fitting 80,pipe 81, L fitting 81, pipe 82 and cock 83 to the before mentionedsystem of gas distributing pipes. Fittings and 80 are for strength,secured together by pipe 56, having gas tight plug 56, therein.

Referring to Figs. 5 and 16 respectively, connected with fittings 31 and80 are the relief pipes 46 and 46, extending downward therefrom, throughand secured to the top of water seal box 47 provided with water 48therein and with fill tube 49. Said water 48 rises in said water sealpipes and forms water seals 50 and 50, respectively therein.

Storage bell 34 is provided with the following described pressurerelieving means. Sleeve guide'51 has the closed upper end thereofsecured to the top of said bell and its lower end braced by transversebrace 52,

the ends of which are secured to the interior of said bell. Said sleevehas apertures 51 formed through the lower portion thereof, adapted to belifted by bell 34 above the top of water seal 33. Said sleeve isslidably guided on guide pipe 53, which acts both as a guide for saidbell and as an exhaust or relief pipe therefor, when said sleeve guideapertures are raised by excessive pressure of gas in said bell, aspreviously stated. Referring to Fig. 16, the lower end of said guidepipe is connected with the following pressure relief and exhaustconducting parts, connected in the order named z-fitting 54, relief pipe55, fitting 57, exhaust pipe 58, L fitting 59 and vertical exhaust pipe60. With the lower portion of fitting 57 is connected the relief nipple60 extending downward therefrom, through and secured to the top of box47, for communicatively connecting the upper portion of said box withthe previously described exhaust conducting parts. By pass exhaust pipes60 connect said exhaust conducting parts with gas directing cock 28, asseen in Figs. 3, and. 4.

Referring to Figs. 5 and 15, water seal cap 35 is lifted above waterseal 33 for opening pipe 32, when it is desired to exhaust gas from bell34, through said pipe, and pipe 30, into and through cook 28, and thepreviously described by-pass exhaust conducting means. Said cap 35 isthus lifted by connecting rod 36, pivotally connecting said cap withcrank 37, formed with counter-shaft 38, rotatably mounted on the bottomof tank 33 and having crank 39 formed on the opposite end thereof. Thefree end of said crank is connected by pull wire 40, (indicated by dotand dash line in ,Fig. 1,) with crank 41, formed with shaft 42, (seeFig. 2,) rotatably mounted on water tank 10 and provided with crank 43on the opposite end thereof, connected by pull rod 44 with the centralportion of treadle 45, one end of which is pivotally secured to leg 77,(see Fig. 1,) and the other or free end adapted to be depressed byhandle 65 when the same is rotated to the full limit of its rotation,with 65 in register with point 66.

Cook gate 29 is provided with stem 61, the outer end portion of which isrotatably sup ported in box 62, secured to stand piece 63 and hasgrooved crank segment 64 secured on the outer end thereof. Said segmentis provided with crank handle 65, secured thereto and with pointer 65adapted to be moved by said segment into register with the points 66",66 and 66 on index plate 66 and thereby show the position to which cockgate 29 is rotated, asseen in Fig. 1. Said index plate is secured tostand piece 63. Rotatably mounted on said index plate, below point 66 isthe grooved pulley 87. The lower end of operating cable 84 is secured tosegment 64, near pointer 65, and is passed over and on said segment,thence under pulley 67 and extends upward therefrom over pulleys 85rotatably secured to any fixed object 85. Said cable is thus extended toany desired point distant from the described machine for rotating saidcock gate. Said cable is provided with handle 84, heavy of weight forkeeping said cable taut, and by which to pull said cable, when the crankhandle 65 is inaccessable by reason of fire.

Referring to Fig. 1, waste cock 7 is provided with crank 7 b connectedby connect-ing rod 7 with crank 7 secured on the outer end of cock stem61, for automatically opening said cock when pointer is rotated to point66 with cock gate 29 in the position seen in Fig. 5, for draining waterfrom compartment 5 into bucket 7, when the described generator is to beemptied and be recharged with fresh carbid as hereinafter described.Referring to Fig. 1, bell guide gate 67 is secured 011 the stem 9 ofwater feed cock 9, and is provided with connecting rod 67 connecting theright end of same with crank 67, secured on cock stem 61, for rotatingboth the stem of cock 9 and the gate 67 when stem 61 is rotated aspreviously described. This latter operation closes feed .water cock 9and removes gate 67 from in front of space 23 for allowing passagetherethrough of bell guide wheel 2 1.

The lower end of valve lever rod 68 is pivotally secured at 68 to gate67, and extends therefrom upward through apertured rotatable guide stud69, rotatably secured to valve lever 16, best seen in Fig. 12. Said rod68 is provided with stud pin 68 secured therein and adapted to liftlever 16 from the position indicated by dotted lines 16 seen in Fig. 1,to the position seen in Fig. 5, when cock gate 29 is reversely rotated.Rod 68 has pull pin 68, adapted to pull weight 70 downward. Pawlreleasing weight 70 is slidably mounted on the upper end portion of rod68 and has its downward movement thereon limited by yoke 70, secured atits lower end to said weight and passed over and adapted to rest on theupper end of said rod. Said weight is adapted to gravitate onto pawllever 18, overcome the weight of pawl weight 18 and rotate said pawl onpivot 19, from engagement with ratchets 17, for lowering lever 16 by thegravity thereof, from the position seen at 16 to the position indicatedby dotted lines 16 in Fig. 1, for removing said lever from over bell 2,while the previously described open ations of recharging are beingperformed.

Vater seal tank 33 is provided with overflow pipe 72, which passesthrough tank 10 and is adapted to direct any excess of water from tank33 into bucket 73.

The heretofore described parts of the machine are mounted on a standcomprising ring 74, beneath tank 33, ring beneath tank 1, the rear standpiece 76 and the front stand piece 63, by which said rings are securedtogether, and the three legs 77 and the leg 77 on which said rings aremounted. Said legs have openings 7 7 therethrough, for reception andsupportof the pipes. Bell 2 is lagged with sheet asbestos 2, coveredwith sheet metal jacket 2, said acket having a. row of apertures 2,formed therethrough around and near the lower edge water, caused by fireoutside the machine would generate steam in said asbestos, which escapestherefrom through apertures 2 formed through the top of said jacket.Bell 3 1 is provided with asbestos lagging 34, covered by jacket 3 1",provided with apertures 34 and 34 identically the same in con structionand operation as the lagging and jacketing of hell 2. Space tiller 2 iscarried by bell 2, for expelling gas from the generator, when inposition seen in Fig. 5.

In the operation of my invention, with the parts in position seen inFig. 1, water is fed as described on carbid 3", thereby generating gas,which passes through the gas conducting means from bell 2 into hell 3%,being scrubbed cooled and cleaned by passage through water 33. Said gaspasses therefrom through the gas outlet conducting means, from whencesaid gas is used through distributing means not shown, until all of saidcarbid is exhausted of gas. When said carbid has thus been slaked orexhausted, the described generator is recharged with fresh carbid, inthe following manner. Generator bell 2 is forced downward, from theposition seen in Fig. 1 to the position seen in Fig. 5 and laterallyrotated to the position seen in Fig. '7, with guide wheels 241 in spaces22? and 23 and held down by the concaved ends 22" and 23 of guides 22"and 23. This forces all the gas from bell 2, through the described gasconducting means into storage bell 3st. At this juncture it will beunderstood that gate 67 prevents farther movement of wheels 24. Theoperator now, by handle 65 rotates cock gate 29 from the position seenin Figs. 1 and 8 to the position seen in Figs. 5 and 9; thereby preventsback flow of gas from bell 34, and by the previously described rod andcrank connection, closes feed water cock 9, lowers rod 68, and at thesame time opens waste water cook 7 and rotates gate 67 from in front ofspace 23". As rod 68 is thus lowered the same carries lifting stud 68downward and at the same time lowers pawl releasing weight 70 onto pawllever 18, by the gravity of which said pawl is released from ratchets17, thus removing all support from beneath the free cleaned, rechargedwith fresh carbid 3", after which said pans, pan retainer and bell 2 arereplaced.

After the described recharging is done, the operator, by handle 65rotates cock gate 29 back from the position seen in Fig. 9 to theposition seen in Fig. 8, and thereby reestablishes communication betweenbells 2 and 34. At the same time the reverse movement of the partsconnected with handle 65, moves said parts back to the position seen inFig. 1, except the parts lifted by rod 68, which are lifted by lift stud68, (on said rod) to the position seen in Fig. 5, with the free endportion of lever 16 supported by pawl 18 resting in one of the ratchets17. Gas is again generated as previously described, and raises bell 2until the top of same lifts the weighted end 16 of lever 16; while suchis done the gravity of said lever and its attached parts causes valve 11to thereby be closed.

The closing of valve 11, as previously described, stops feeding of waterfrom tank 10 onto carbid 3, but the previously fed water continues toact on said fresh carbid for a short time thereafter, continuing thegeneration ofgas and thereby raises bell 2 which lifts the free end oflever 16 and carries pawl 18 into engagement with the next, higherratchet 17.

When pressure of gas in bell 2 is lowered; by use of same through cock83, (see Figs. 1, 2, and 16) said bell is thereby caused to movedownward from weighted end 16 of lever; 16, which latter is fulcrumed onpawl pivot; 19, supported by engagement of pawl 18; with said ratchet17. The thus supportedj lever 16, by reason of gravity of weight 16;opens valve 11, again admitting water into; compartment 5 onto carbid 3by which gasi is again generated. These operations arei repeated untilthe upward travel of lever 16; is stopped by stud 17", which therebystopsf farther upward movement of bell 2, after which any excessiveamount of gas gener-l ated, passes from bell 2 through the previouslydescribed gas conducting means into? storage bell 34, thereby causingsaid bell also to rise, with the parts in position seen in Fig. l. 1

In gas machines of this character, where water is continually fed ontothe carbid, throughout the full upward travel of the generator bell, thevolume of water in the lower one of pans 3 becomes so excessive as tocause generation of gas after both the generator bell and the storagebell have thereby been caused to reach the full limit of their upwardtravel, and frequently surplus gas is exhausted through the previouslydescribed storage bell relieving means, thereby entailing a waste ofcarbid. In such machines this waste of carbid, caused by abnormalgeneration of gas, takes place most frequently in cases where gas is notused for some length of time after recharging the generator. All of thesaid abnormal generation of gas and consequent loss of carbid isobviated by the use of the previously described feed-water valvecontrolling means. When it is desired to exhaust all the gas from theentire machine, cock gate 29 is rotated, either by crank handle 65 or byhandle 84, from the position seen in Figs. 1 and 8 to the position seenin Fig. 10, indicated by pointer 65 being in register with point 66, onindex plate 66. This position of said cock gate 29 places the previouslydescribed gas conducting means in communication with said cock, bothfrom bells 2 and 34 and opens communication be tween the same andby-pass exhaust conducting pipes leading into exhaust pipe 60, throughwhich all of said gas is eX- hausted. into the open air. Pipe 32 forms apart of said gas conducting means and to permit said gas to exhausttherethrough, is opened at its upper end by lifting cap 35 above waterseal 33. This is done by movement of crank handle against the free endof treadle 45, connected with said cap by the previously described rod,shaft and crank connections. This latter movement of the parts, by thepreviously described rod and crank connections with cock stem 61, causesfeed water cock stem 9*, gate 67, rod 68 and the weighted end 16 oflever 16, to move from the position seen in Fig. 1, to the previouslydescribed position to which the parts are moved for recharging thegenerator. During said movement, waste water cock is opened whilepointer 65 is passing point 66 and again closed, thereby draining asmall amount of water from compartment 5 into bucket 7 This movement ofthe parts closes the feed water conducting means, lowers the water incompartment 5, and thereby stopsfurther generation of gas.

During the formerly described operations of recharging the generator,should the operator inadvertently rotate the cock gate 29 back from theposition seen in Figs. 5 and 9, to the position seen in Fig. 8, beforereplacing bell 2 in the generator, pressure of gas in cap 35 would findexit therefrom through pipes 32 and 30, cock 28 and pipes 27 and 26, inan inappreciable quantity. When such is done pressure of gas in storagebell 34 above the water seal 33, (see Fig. 5,) forces a portion of thewater forming said water seal into cap 35, and forms water seal 33",(see Fig. 15,) therein and around the upper end portion of pipe 32,effectually preventing back flow of gas therethrough from bell 34, anddanger from liberated gas.

While I have shown and described the generator bell guiding means in theforegoing manner, it is evident that different forms of guiding members,carried by said bell, and differently supported vertical guides, withopen spaces thereunder, could be constructed without departing from thespirit of my invention. One of such different forms of guiding membersand differently supported guides is seen in Figs. 17 and 18, in whichhandle bar 25 is secured on the top of bell 2 and has a guiding member24 and a shank end portion 25 with a space between them, formed on eachend thereof, and a handle 25 on each of said shank end portions.Vertical guides 22 and 23 are supported respectively by the offsets 22and 23 which form spaces 22 and 28' respectively beneath the lower endsof said vertical guides, one of which is closed by movable gate 67, theconstruction and oper ation of which is identical with gate 67 seen inFig. 1 and previously described. The same is true of the supports belowsaid offsets.

Vertical guides 22 and 23 extend upward from their respective offsets,between the previously described members 2 1 and shank end portions 25for vertically guiding the same, the upward travel of which is limitedby stop caps 22 and 23 secured on the respective upper ends of verticalguides 22 and 23, seen in Fig. 17 and removed from said guides in Fig.18, to avoid obscurity.
